LUBRICATOR.

Application filed June 13,1906. $1.1

Be it known that we, Enwann REBER and Evnnnrr C. CLARK, citizens ot thel nited States residents of San Bernardino. in the county of SanBernardino and State of Cali- 1 tam new and useful fornia, have made a cInvention in Lubricators; and we declare the "following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it appertains to make and use the invention,i rence being had to the accompanying drawing, and to letters or figuresof reference marked thereon, which form a part of this specifica tion.

The drawing represents a vertical sectional view of the lubricatcr.

The invention has relation to that class of lubricators which feed bydisplacement of the oil by the water oi OOIllllS&t";ll; and it consistsin the novel construction and combinations of parts, as hereinafter setforth.

The object of the invention is to providmeans for filling theoil-chamber of the lubricat-or, whereby this operation will bematerially facilitated and some of the obiections to the or inary modeoi filling av ided.

in the accompanying drawing, illustrating the invention, the letter adesignates the oilchamber of a lubricate-r, having thecondensing-chamber 7), from which a pipe 0 extends nearly to the bottomof the oil-chamber. A pipe (1, opening in the upper part at theoilchalnber. communicates with the feed-(hamber e and feed-passage f,which is p vided with a regulating-valve g. the oil-chamber is providedwith a wasteplug 71.

To the bottom oi the oil-chamber is secured an outlet-pipe 7t, whichopens at said bottom into said chamber. vided at its lower end with aunion m, and to said bottom is also secured an inlet pipe p,

said pipe having an upward extension r, opening in the upper portion ofthe oil-chamber, and being provided at its lower end portion with aunion n.

The bottom of This pipe is pro- I Specification of Letters latent,

l l l l l l I'atcnted Feb. 5. 1x073 tached to the lower ends of theoutlet-pipe Z; and the inlet-pipe p of the oil-chamber by means of theunions m and n. This tank is therefore removable from the oil-chan1berof the lubricator. It is provided with a glass gage at one end, asindicated at s, and with a waste-plug w. The valve of the pipe at isshown at t and the valve of the pipe 4; at Q. The top of the tank isprovided with a fillingpassage and plug, as indicated at 0.

The supply-tank having been filled with oil and attached to thelubricator by means of the unions is ready for use. Its valves arenormally closed. W hen the oil is exhausted l from the lubricator and itis full of water, the

valve t is first opened to equalize the pressure, and then the valve qis opened. The water from the lubricator descending through itsoutlet-pipe it forces the oil from the feedtank rapidly upward into theoilchamber through the inlet-pipe p and its extension 1", and when thegage 8 indicates that the oilchamber is full the lubricator is ready foraction.

The supply-tank can be kept filled, the water of condensation beingdrawn off by means of the valved waste-passage in its bottom, or it maybe detached from the lubricator and replaced by a filled tank kept inreserve. This filling-tank is readily applied to a lubricator and isdesigned to save time and prevent waste of oil and accidents from theescape of hot oil. It is also of importance in preventing the breakageof gageglasses, which is often caused by irregular 2 represents anoil-tank of proper capacity to provide oil for filling the oil-chamoerof the lubricator. To the top of the tank is secured t heupward-extending valved inletpipe u and the upward-extending valvedoutlet-pipe o, these pipes having threaded ends and being designed,respectively, to be at- Cooling or heating, and in avoiding delay inwaiting for a lubricator to cool before filling.

llavin thus described the invention, what we claim, and desire to secureby Letters Patent, is-

1. In a lubricator, the combination with an oil-chamber having anoil-inlet pipe extending through its bottom wall, and awateroutlet pipeextending through its bottom wall, of a filling-tank having anupward-extending valved oil-pipe having detachable means of connectionwith said oil-inlet pipe of the oilchamber, and an upward-extendingvalved water-pipe having detachable means of connection with saidwater-outlet pipe of the oilchamber.

2. A lubricator having an oil-chamber provided with oil inlet and outletpipes extending upward within the same to near the top thereof, alateral feed-passage having communication with the lower end of saidoiloutlet pipe and provided with a valve, said oil-inlet pipe having alower extension through the bottom of the oil-chamber threaded at itslower end, said oil-chamber having a water-outlet pipe threaded at itslower end, and means for supplying the oilchamber with water ofcondensation having connection with a steam-supply.

3. In a lubricator, the combination of a filling-tank, an oil-chamberhaving inlet and outlet pipes for oil extending upward within thechamber to near the top thereof, said inlet-pipe having a bottomextension to the filling-tank provided with a valve, a feedpassage atone side of said oil-chamber having communication with the lower end ofsaid outlet-pipe and having a valve in its lower end portion, awater-outlet-pipe connection between the oil-chamber and thefilling-tank having a valve, a water-supply chamber communicating with asteam-supply from the boiler, and having a pipe extGDClID to near thebottom ol the o1l-cham her and a pipe communicating with the upperportion of said feed-passage.

4. In a lubricator, the combination with an oil-chamber having anoil-inlet pipe and a water-outlet pipe, of a filling-tank having anupward extending valved oil -supply pipe having detachable means ofconnection with said oil-inlet pipe, and an upward-extending valvedwater-inlet pipe having detachable means of connection with thewater-outlet pipe of the oil-chamber.

In testimony whereof we affix our signatures in presence of twowitnesses.
